Thanks Jason and Kenny. I had found that thread on the fuel issue. I am still chasing my tail on the different outcomes on the fuel solenoid. I can confirm that I get the pull function but definitely not the hold. I am still trying to determine if it is a problem in the circuit or the solenoid. The diode I found does not appear to be the V4 diode in this drawing.
The wire colors do not match. But with the 2nd article Kenny posted, I see that there are others. I guess I need to dig further into that harness.
I also can't identify the "fuel solenoid relay switch" mentioned in the article Kenny shared. I have also seen mention of a 15A fuse, but I can not identify a fuse that is dedicated to the fuel circuit. Everything else is working on this tractor.
Needless to say, this would be easier with the shop manual. I definitely need to get one. If I am going to buy the CD, can I buy from somewhere that will let me download instead of waiting for the mail?
Either way, would the shop manual have good enough pictures to help me identify the specific locations of the various relays, control modules and diodes? That area of the tractor is a huge mess. Nothing has labels, the wiring is extremely tight, and it is very difficult to see wire colors. OK, I am done whining.
